ABSTRACT

INTRODUCTION: One of the most debilitating problems encountered by people with multiple sclerosis (MS) is the loss of balance and coordination. Our study aimed to comprehensively evaluate the effectiveness of one year of Tai-chi exercise in patients with MS using both subjective and objective methods, including posturography. METHODS: This was a single-group longitudinal one-year study performed from the 1st of January 2019 to the 1st of January 2020. The primary outcomes of interest were the Mini-Balance Evaluation Systems Test (Mini-BESTest) and static posturography measures as objective methods to detect subtle changes associated with postural control/balance impairment. Secondary outcomes were measures of depression, anxiety, cognitive performance, and quality of life. All objective and subjective parameters were assessed four times: at baseline, and after three, six and 12 months of regular Tai-chi training. The difference was calculated as a subtraction of baseline values from every timepoint value for each measurement. If the normality test was passed, parametric one-sample t-test was used, if failed, Wilcoxon signed ranks test was used to test the difference between the baseline and each timepoint. Alpha was set to 0.017 using Bonferroni correction for multiple comparisons. RESULTS: Out of 25 patients with MS enrolled, 15 women with MS (mean age 44.27 years) were included for statistical analyses after completing the 12-month program. After 12 months, significant improvements were found in all objective balance and gait tests: Mini-BESTest (p<0.001), static posturography measures (total area of the centre of foot pressure - TA; p = 0.015), 25 Feet Walk Test (25FWT; p = 0.001), anxiety (Beck Anxiety Inventory - BAI; p = 0.005) and cognition tests (Paced Auditory Serial Addition Test - PASAT; p = 0.003). Measures of depression (Beck Depression Inventory - BDI; p = 0.071), cognition (Symbol Digit Modalities Test - SDMT; p = 0.079), and health-related quality of life (European Quality of Life 5-Dimensions Questionnaire - EQ-5D-5L; p = 0.095) showed a trend of improvement but were not significant, which could be the result of a small sample and increased bias due the type II error. CONCLUSION: According to these preliminary results, this study indicates the possible beneficial effects of long-term Tai-chi training on patients with MS. Although these findings need to be confirmed by further studies with a larger sample of participants of both genders and require more rigorous randomized controlled trials (RCT) design, our findings support the recommendation of regular and long-term Tai-chi exercise in patients with MS.

ABSTRACT

OBJECTIVES: Neuroinflammation represents one of the two major pathological components of multiple sclerosis (MS). The aim of our study was to find the role of the late pro-inflammatory cytokine HMGB1 (high mobility group box) in MS pathogenesis. SUBJECTS AND METHODS: A total of 165 patients from three MS centers in Slovakia were enrolled in the study. Patients underwent a complex clinical investigation and their plasma levels of HMGB1 were analyzed by a sandwich ELISA test. RESULTS: MS patients had 4.5 times higher plasma level of HMGB1 (median, 13.529 ng/mL; IQR = 2.330-113.45) than healthy controls (median, 2.999 ng/mL; IQR = 1.686-9.844; P < 0.0001). The concentrations of HMGB1 were significantly associated with increased number of affected areas diagnosed by MRI (P < 0.0001) (the median for one affected area, 4.205 ng/mL; median for five affected areas, 17.843 ng/mL; P < 0.05). Patients with at least one active lesion in any of the affected areas in the brain had significantly higher plasma levels of HMGB1 (median, 20.118 ng/mL; IQR, 3.693-100.12) than those without any active lesion (median, 16.695 ng/mL; IQR, 3.255-113.45; P < 0.0235). We found also a very highly significant association of HMGB1 plasma levels with clinical condition expressed as EDSS (expanded disability status scale) (P < 0.0001); patients with higher EDSS had higher levels of HMGB1 (EDSS ≤ 2.5, 11.648 ng/mL vs. EDSS ≥ 3, 17.549 ng/mL; P = 0.0115). CONCLUSION: Our results suggest chronic low-grade inflammation in MS patients that correlates with clinical conditions of MS patients, and for HMGB1 as a possible target molecule in future therapy.

ABSTRACT

Rasmussen's encephalitis is a rare autoimmune encephalitis usually involving one brain hemisphere, presenting with refractory epileptic seizures, and neurological and cognitive decline. Only 10% of cases start later in adolescence/adulthood. The only effective treatment for refractory seizures in childhood is hemispherectomy. For late-onset cases with mild neurological deficit the hemispherectomy is usually postponed because of its severe consequences. Immunotherapy shows some temporal effect for seizure control and slowing the brain atrophy, mainly in late onset Rasmussen's encephalitis. We report a patient with late onset Rasmussen´s encephalitis with anti-ganglioside IgGQ1b and anti-GAD antibodies positivity, who failed immunotherapy with cytostatics, immunoglobulins and steroids. Anti-ganglioside IgGQ1b antibodies are typically associated with a Miller-Fisher variant of Guillain-Barre syndrome and Bickerstaff's brainstem encephalitis. The association with Rasmussen´s encephalitis was not described before. Patient´s neurological deficit was mild and hemispherectomy was refused. The treatment with rituximab, an anti-CD20+ monoclonal antibody, led to 36-month control of seizures without any signs of progression of neurological deficit and MRI brain atrophy. Although the treatment is associated with long term B-cells depletion, patient doesn´t suffer from any clinically relevant infection. The biological treatment with monoclonal antibodies might be the way to stabilize patients with Rasmussen´s encephalitis, mainly late-onset, to prevent them from harmful and devastating hemispherectomy.
